Bethany Mennonite Church (General Conference Mennonite) of Quakertown, Bucks County, Pennsylvania, was a member of the Eastern District Conference. On 27 December 1898 a group of Mennonites living in Quakertown met in St. Paul's Evangelical Church for the purpose of taking preliminary steps toward organizing a congregation. This organization was finally effected at another meeting on 2 January 1899. Services had previously been held occasionally in the St. Paul's church, but action was now taken to have regular services. Later in the same year the above building was purchased and remodeled. The Sunday school, organized in 1895, and the Young People's Society, organized in 1897, antedated the congregation and gave impetus to its organization.

The membership in 1908 was 62, and in 1953 was 156. The common names in the 1950s were Shelly, Boorse, Landis, Moyer, George, and Martin.

The Bethany congregation merged with the Flatland Mennonite Church to form the United Mennonite Church at 180 West Thatcher Road, Quakertown. The latter congregation withdrew from the Eastern District in 2002 and became a founding member of the Alliance of Mennonite Evangelical Congregations, a conservative group of congregations opposed to the theological diversity within the new Mennonite Church USA.
